Schritte zur Lösung

\int_{- 2}^{2} x^{2} - 4 x d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 2}^{2} x^{2} d x - \int_{- 2}^{2} 4 x d x

\int_{- 2}^{2} x^{2} d x = \frac{16}{3}

\int_{- 2}^{2} 4 x d x = 0

= \frac{16}{3} - 0

Vereinfache

= \frac{16}{3}

\int_{0}^{s i n (θ)} sec^{2} (y) d y

\int_{- 2}^{\infty} e^{- 3 x} d x

\int_{0}^{\frac{4}{11}} \frac{1}{121 x ^{2} + 16} d x

\int_{1}^{3} \frac{x ^{3} - 1}{x ^{2} - 1} d x

\int_{2}^{7} \frac{8 x}{x ^{2} + 1} d x
